JOHN J'. TARTT, OF LOS ANGELES, CALIFORNIA.

PANORAMAGRAPH.

To all whom t may concern.'

Be it known that I, JOHN J. TARTT, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Panoramagraph, of which the following f bols on a. screen or other plane surface, the

image of these words or symbols traveling across the surface of the screen at a constant rate so that long messages may be so exhibited. Further objects and advantages will be evident hereinafter.

In the drawings which are for illustrative purposes only 1,-

Figure 1 is a plan View of the invention together with a portion of the illuminating means. l I

Fig. 2 is a side elevation of the same invention, a portion-thereof being shown in section to better illust-rate the invent-ion.

Fig. 3 is a Viewr of the invention as seen from the lamp house, a portion thereof being broken away to better illustrate the internal structure.

Fig. 4 is a View of a portion of the perforated tape.

, Fig; 5 is a somewhat diagrammatic view of the screen. l y

Broadly considered the invention consists of an illuminating means 11 which may be preferably in the form of an arc lamp 12 as shown, or which may consist of any other suitable luminous source.v Acondensing lens 13 .serves to direct the'light from the source 12 through a flexible tape 14,'this tape being perforated as shown at 15 in Fig. 1 with the words or symbols which it is desired to project. The tape 14 is kept in continuous mo- -tion by means of a motor 16, the tape being Wound and unwound fromdruins 17 and 18 driven by the motor. lenses are mounted in a these lenses throwing the image of the words orsymbols carried on the tape 14 ona snitable screen.

In the form of the invention illustrated in the drawings a `table 20 is provided, this table having suitable legs 21 and carrying the lamp house 22 in which the arc lamp 12 is placed. The lens 13lis mounted in a pro- Suitable projection projecting tube 19,

jection on the front of the lamp house 22. Shields 23 and 24.- are placed over the outer lens 25 forming an elongated rectangular aperture 26. A shutter 27 is provided so placed that it can be pushed down to shut off this light if desired. An aperture. plate 2T is secured to a base 28, mounted on the table 20. this aperture plate having an aperture 29. The tape 11 passes over the plate 2T in such a position that the words or s vmbols 15 pass in front of the aperture 29. Spring fingers 30 are secured to the aperture plate 2T above the aperture 29, these spring `fingers carrying a plate 31 which rests upon the tape holding it in close contact with the aperture plate 27.

A bracket 32 is secured to the base 28, and extends upwardly being connected to the aperture u bracket 3 Vertical shafts 31 and 35 are carried in bearings 36 formed in the upper bearing bracket 33, these shafts being journaled at their lower end 38 on the base 28. Mounted on t-he shafts 31 and 35 are guide spools 37 and 38, these spools having a raised rim between which the tape 11 moves.

Mounted on the shaft 35 is a spur gear 39,

l gear 46 turning freelyv on a short shaft l? rigidly secured to a bracket 18 which is secured by means of screws 19 to the base 28. The bevel gear 16 has a groove cut therein in such a. shape as to receive a round belt- 50, this belt passing over an idler 51 turning on a fixed shaft 52 which is supported in a bracket 53. rl`he bracket 53 is secured by means of screws 51 to the side of the base 28. The belt 50 also passes over a belt wheel 55 which is secured t-o the drinn 17. Rigidly mounted on the sha-ft 11 is a worm gear 5G, this worm gear being driven by a worm 57, carried on the shaft of the motor 16. Mounted on a bracket pin carried on a bracket 58, secured to the base 28, is a color changing screen 59, this screen consisting preferably of a metal memberhaving a plurality of colored glass members 60 secured therein, these colored glass members 60 being so located that they can be successively rotated into place in front of the projecting tube 19. so that the light which is projected late 27 bv an u `)er bearinO',

therethrough can be suitably colored, the' words or symbols appearing on the screen being thus shown in colors whichvcan be changed by the operator whenever desired.

The roll 17 is mounted on a shaft 61 carried in brack`ets 62 and 63, these brackets beling secured to the side of the table`20 by `screws 64. The bracket 62 extends'upwardly.

and carries an idler pulley 65 which rotates freely ona pin 66, secured in the bracket 62. Pivoted on the shaft 61 adjacent to the f bracket- 63 4is a pivoted arm 67 which is forced in the direction` of the arrows 68 by the coil spring 69. Carried on the arm 67 is a pin 70 on which is mounted a loose pulley 71. Theltape 14 passes from the 4aperture 29 around the -wheel 37, around the pulley 651*7 and downwardly around the drum 18, it then passes in successive wraps around so that it is-continuous, this tape being perforated with a series yof words or symbols. The drum 18 is mounted on a shaft 80 which is carried in arms 81, these arms'be-V,

ing slidably mounted, in the legs 21 of the this length of tape, and long lengths ',ofltape can be accommodated in the machine sorthat extended messa A may be thrown onthe screen as desireA The method of operation :is as follows;

The motor 16 is supplied with current from any suitable source, and 'the-.arcflamp 12 itsv energized so that it throws'y a beam of light against the condensers `13. `The motor 16 drives the shaft 41 through the worm 157 and theworm gear 56, and the shaft-,41 drives'` the shaft 35 through the gears yeiland 39. The shaft 35 drives the belt 50; passing around the groove in the bevel gear 46,` and the pulley 55 drives the drum 17, thetdrum 18 turning freely and being driven through1 the tape v14. The tape is therefore moved in the direction of thearrows shown in the tube -19 through one of the colo .day of August, 1915.

light through these perforations is directed by the projecting lenses in the pro'ecting glass members against the screen. As a result `t-he image of thewordsA or symbols on the' tape 14 is thrown against the screen, these lmages traveling across the screen from right to left at a slow .rate of speed so that new 60 words orl symbols are constantly appearing on the screen. v f a One. convenient. application of the invention is for advertising purposes, the panora-magraph being set up in such a position that it can throw its imageon a screen or blank wall located in a position where it can be' seen by the public. vlVhen so locatedK the panoramagraph can be put in operation and will operate with .very little attention, 70r

successively throwing upon the screen 'the -words or symbols perforated in the tape 14,

the words or symbols constituting advertising matter. l
